Fitting a new door frame to the 2 storey offshot kitchen. Like most round here, the offshot has sunk a couple of inches over the years (built 1890), meaning the frame is about 1.5cm out in the opening.
Do I level the frame to a spirit level, or the opening? I've done it to the spirit level, thinking it wouldn't be that noticeable, and out of level would create door hanging problems. But now it's in (not permanently fixed) it does look odd to my eye.
